Is it real? Edit: How much better is Claude Fable 5 vs. Opus 4.8? (Anthropic’s launch benchmarks, June 9, 2026) • SWE-Bench Pro (agentic coding): 80.3% vs. 69.2% for Opus 4.8 • FrontierCode Diamond: 29.3% vs. 13.4% — more than double • Core pattern: the longer and more complex the task, the larger Fable 5’s lead; on short, well-scoped tasks the two are much closer In practice: noticeably better on long multi-step work (migrations, feature builds, complex pipelines); barely different for quick, simple tasks. Caveat: these are Anthropic’s own benchmarks — directionally correct, but vendor numbers.

Browsing on Skool can be a bit overwhelming with it's UI (my eyes need a dark theme) and the great volume of stuff on CliefNotes makes jumping in daunting, especially if you're away for more than a day, so I wanted something that made browsing feel effortless and easier to navigate and see things and keep posts around that I wanted to dig into a bit more. So I built a browser extension that gives me a faster, cleaner view over the same Skool feed, posts, and comments. The catch: I don't know web code. I don't know APIs. But I've learned that knowing what I *don't* know is exactly where AI earns its keep. I know how to troubleshoot — so I can tell it what's happening, what's breaking, what information I need next — and it hands me the technical roadmap I don't have. I wasn't writing this thing so much as steering it. The part that nearly broke me was comments. A post with over 100 replies would render only 50, and I couldn't see why — Claude almost threw in the towel but I persisted because one thing I've learned working Game Dev is that if you can see something on the screen then that data exsists somewhere, you just have to figure out where to look. The takeway I want to flag is to think about pointing AI at your pain points, the best things to come out of using ai for me have been asking "What if?" And a lot of the amazing things people have created in here follow the same pattern. I also want to highlight this post by @Jason Jennings : https://www.skool.com/cliefnotes/sortable-posts-clief-notes-sidebar-easy-copypaste I was in the middle of my build when I came across it and I folded some of the sorting options into the extension because I thought they were great I built it to be shared — open source, free, and I'll keep updating as I go, genuinely open to suggestions. Only caveat is it can only do what Skool's API allows. Also I use Firefox mainly and it's easier to sign a native browser extension for firefox so you can install directly using the .xpi link in my repo, for Chrome you'll have to download the .zip and in Chrome set it to developer mode and you can sideload an unpacked extension (instructions should also be in the zip).
